Australia's weather doesn't go easy on anything mounted on your roof. Between summer storms, coastal winds, hailstorms, and the relentless UV exposure that comes with living under some of the harshest sun on the planet, your TV antenna takes a beating year after year.
A well-installed antenna can handle most of what Australian weather throws at it. But "well-installed" is doing a lot of work in that sentence.
Here's how to make sure your antenna survives storm season and what to do if it doesn't.

Why Storms Are Hard on Antennas
Your TV antenna sits at the highest point of your roof, which is exactly where it needs to be for good reception, but also exactly where it's most exposed to wind, rain, lightning, and hail.
Strong wind is the biggest threat. Even if the wind doesn't snap the antenna off its mount, it can:
- →Gradually loosen bracket bolts over time
- →Push the antenna out of alignment by a few degrees (enough to ruin digital reception)
- →Flex the mounting mast until it develops metal fatigue
- →Vibrate connections loose at the antenna head and cable join
Rain and humidity cause corrosion, particularly on cheaper antennas with uncoated metal elements. Salt air near the coast accelerates this dramatically.
Hail can physically break antenna elements, while lightning strikes, even nearby ones, can send power surges through your antenna system that destroy amplifiers, splitters, and even your TV.
Before Storm Season: Preparation
Get a Professional Inspection
If your antenna is more than five years old or you've never had it checked, book a professional inspection before storm season begins.
A technician will check:
- →The mounting bracket and bolts for corrosion or looseness
- →Every element on the antenna for cracks or damage
- →That the mast is straight and securely braced
- →All cable connections for weatherproofing
Check Your Mounting Hardware
The bracket that holds your antenna to the roof is the most structurally critical component. It needs to be firmly attached to the roof structure, not just to a tile or sheet of roofing material, but to the timber or steel framing beneath.
Bracket bolts should be tight with no play or wobble in the mount. If the antenna sways visibly in a moderate breeze, the mounting hardware needs attention.
Ensure Weatherproof Connections
Every outdoor cable connection on your antenna system should be protected from moisture. This means using weatherproof F-type connectors, sealing connection points with self-amalgamating tape or silicone, and making sure the cable entry point into your roof space is sealed against rain.
Good to Know
Water getting into a coaxial connection causes corrosion that degrades signal quality progressively. You might not notice the effect immediately, but over a few months, a wet connection can reduce your signal enough to cause pixelation.
During Storms: What to Expect
During a severe storm, some temporary reception disruption is normal and not a sign that anything is wrong with your antenna.
- →Heavy rainfall can scatter signal energy, causing brief pixelation or dropouts
- →Lightning in the area can create electrical interference that disrupts reception momentarily
- →Very strong winds may cause slight vibration in the antenna, which can affect signal stability temporarily
If your reception returns to normal after the storm passes, your antenna is fine. No action is needed.
Lightning Protection
Direct lightning strikes on antennas are relatively rare, but the damage is severe when they occur. A direct strike can destroy every electronic component in your antenna system, including amplifiers, splitters, power supplies, and potentially your TV itself.
Surge protection power boards at your TV outlet offer some defence, but they won't stop a direct lightning surge coming down the antenna cable.
Important
The simplest precaution during a severe electrical storm is to unplug your TV and any connected equipment from both the power point and the antenna wall outlet. This physically disconnects your equipment from any surge path.
After a Storm: What to Check
Once the weather clears, do a visual inspection from the ground:
- →Is the antenna still upright and pointing in the same direction as before?
- →Are all the elements (horizontal rods) intact?
- →Is the mounting mast straight?
- →Can you see any obvious damage to cables or connections?
- →Are there broken tiles or roofing material around the antenna's base?
If the antenna has visibly moved, is leaning, or has broken elements, you'll need a professional repair. Don't attempt to get on the roof yourself after a storm, wet surfaces, debris, and potentially damaged roof structures make this especially dangerous.
If the antenna looks fine from the ground but your reception has degraded, the antenna may have shifted just enough to affect alignment. A professional realignment is a quick fix.
Insurance and Storm Damage
Home and contents insurance policies in Australia generally cover storm damage to TV antennas, but the details vary between policies.
If you're making an insurance claim, have your antenna technician provide a detailed report of the damage and the repair or replacement required. Photographs of the damage are also helpful for the claims process.
Investing in Storm-Resistant Equipment
If you're installing a new antenna or replacing a storm-damaged one, investing in quality equipment pays off:
- →Australian-made antennas are designed for local weather conditions with corrosion-resistant materials
- →Heavy-duty mounting brackets with stainless steel bolts resist rust far better than cheaper galvanised alternatives
- →Properly braced masts with tensioned guy wires withstand higher wind loads
